For those who believe that the steel in the WTC melted, unlike in every other steel frame building fire:

(Just because a bunch of anti-Bush fanatics raise questions about WTC doesn't mean the questions are silly. There may be much more to 9/11 than meets the eye for reasons having nothing to do with Bush. To me it is odder to suggest that the "black boxes" weren't found than that they were, and the government chooses to conceal that fact for some reason.
It didn't have to Melt. It simply had to bend.
